Cerebral disorders are often associated with disturbance of consciousness. Since the latter could alter the prognosis of physical function, early improvement of consciousness level is important. The present study tested the hypothesis that sitting position improves disturbances of consciousness in patients with cerebral disorders. The subjects were 17 patients with cerebral disorders and disturbances of consciousness. The consciousness level was evaluated in supine position and following a change to sitting position. The consciousness level was evaluated by the Glasgow Coma Scale (GCS). The total, eye opening, and motor GCS scores were significantly higher in the sitting position compared with the supine position. In conclusions, changing from supine to sitting position improves consciousness level in patients with cerebral disorders.
